NIT is quickly ramping up with production of InGaAs stacked sensors

Jul 26, 2022 | News

NIT controls and masters in-house all the design and manufacturing phases of its InGaAs focal plane arrays.

One of the critical steps is the 3D stacking of the photodiode array to the read-out circuit, for which NIT has developed a very innovative flip-chip process ensuring high yield and low cost of production.

The 3D stacking process is able to produce FPA’s from pitch of 7.5um to 15um, studies are underway to lower this limit.
